まとめ
2型糖尿病の閉経後の女性の骨粗鬆症のリスクが増加します. 孤立した肥満は骨密度を保護し,体構成の評価の必要性を強調します.
科学分野:
- 内分泌学
- 高齢者医療
- 骨 の 健康
背景:
- サルコペニック型肥満は 筋肉の量と脂肪の過剰が特徴で 骨の健康に悪影響を及ぼします
- 2型糖尿病 (T2DM) の閉経後の女性は特に脆弱です.
研究 の 目的:
- サルコペニック肥満を含む体組成のフェノタイプと骨のミネラル密度 (BMD) の関係を調査する.
- T2DMの閉経後の女性における異なる体質に関連した骨粗鬆症のリスクを評価する.
主な方法:
- T2DMを患った573人の閉経後の女性の遡及的分析
- 骨格筋質量指数 (ASMI) と体脂肪率 (BFP) によるDXAによる対照群,肥満群,肥満症群,肥満症群に分類する.
- スピアマン相関,ロジスティック回帰,制限立方スライン (RCS) モデルを用いた統計分析.
主要な成果:
- 肥満だけでは,BMDが高く,サルコペニアだけでは,BMDが低かった.
- サルコペニ性肥満は,腰椎と股関節の骨質量 (BMD) が著しく低下し,骨粗鬆症のリスクが増加した (OR=3. 368,P=0. 007).
- 肥満はBMDに対する保護効果を示した (OR=0. 515,P=0. 002).
結論:
- サルコペニック肥満は,T2DMの閉経後の女性の骨粗鬆症のリスクを大幅に高めます.
- 孤立した肥満は骨質に 保護効果をもたらすかもしれません
- 定期的な体質評価は 危険にさらされている個人を特定し 適切な介入を実施するために不可欠です

3.9K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Carbohydrates are polymers composed of molecules containing atoms of carbon, hydrogen and oxygen. One gram of carbohydrate can provide four kilo-calories of energy, which makes it the most efficient instant energy source.
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...

609
The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in...

01:22Diabetes Mellitus: Type 2 and Gestational
2.9K
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

01:40Bone Remodeling
38.5K
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.

01:15Diabetes: Symptoms, Diagnosis, and Complications
685
For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is...
